wedgetypecappels1The standard supply of cappel is as shown below and within reason the eye dimensions can be modified to suit any particular requirement. The cappel limbs can be extended if required to house a hard rubber shock absorber as a means of reducing the effects of high-energy vibration which can cause fatigue failure in ropes.

Standard cappel sizes are for ropes from 16 mm (5/8”) to 64 mm (2 1/8”) but cappels for ropes of greater diameter can be supplied. Cappel wedges can also be supplied with grooves to take ropes of smaller diameter than those shown in the table below.

Cappel limbs and bands are made from 1.5% manganese steel to BS 2772, Part 2, 1989, in the hardened and tempered condition. Wedges and safety block are of mild steel to BS 4360: 1979 Grade 43A and in the normalised condition. All cappels are proof load tested to 2.5 times the safe working load and subjected to magnetic crack detection. Ultrasonic tests can also be carried out if required.

Where conditions warrant we can apply zinc as a protective coating.
